In multiple industries such as packaging, elettronica, and pharmaceuticals, the thermal shrinkage performance of plastic films directly determines the fit, sealability, and appearance integrity of product packaging. The core reason why heat shrink film packaging can closely adhere to products, achieve moisture and dust resistance, and enhance appearance lies in...
In the global logistics supply chain system, the compressive capacity of transport packaging directly determines the safety factor of products during warehousing stacking, loading and unloading, and long-distance transportation. As a core standard developed by ASTM International, ASTM D642 provides a scientific and unified test method for evaluating the compressive...
As an indispensable basic material in modern industry and daily life, plastic films are widely used in various fields such as food packaging, electronic insulation, agricultural mulching films, and medical protection. Their impact resistance directly determines the reliability of products during processing, transportation, and use—insufficient impact resistance of food packaging...
ISO 536 is an international standard titled "Paper and board — Determination of grammage", which specifies the official method for measuring the grammage (also known as basis weight) of paper and board. Grammage is defined as the mass per unit area, usually expressed in grams per square meter (g/m²). The...
In today's increasingly dense global logistics network, a product must go through multiple stages such as loading, unloading, transportation, and storage from the production workshop to the hands of consumers. Unforeseen incidents like drops and impacts are almost inevitable. According to statistics from the China Federation of Logistics and Purchasing,...
In today's era of increasingly frequent global trade, a product often goes through a long and complex transportation chain from the production workshop to the hands of consumers. Risks such as stacking pressure and environmental erosion may cause packaging damage and product loss at any time. ISO 2872 is precisely...
In the paper industry and paper product application fields, the mechanical properties of paper directly determine its practical value and applicable scenarios. As a key indicator for measuring paper "toughness", folding endurance is a core part of the paper quality evaluation system. ISO 5626, as the standard for determining paper...
In the production control, product R&D, and international trade of the paper product industry, unified performance testing standards serve as the core cornerstone for ensuring quality stability and promoting market circulation. ISO 534 Paper and Board - Determination of Thickness, Density and Specific Volume, developed by the International Organization for...
